The evaluation of noise level in hand-held pneumatic tools (rock drill) by "pneurop cagi test code" method
Bibliographic record
Abstract
The noise and vibration created in hand-held pneumatic tools such as Rock drills, used in Lashotor stone mines in Isfahan, is evaluated by PNEUROP CAGI TEST CODE method. Rock Drill produces a continuous noise based on ISO standard and so the total dose of duration and level of the various noises are calculated. The measurements are performed with the center of the machine, 1 meter above a reflecting floor, while the noise assessment is done on the spherical area. Sound power level is calculated by using a sound pressure level so that the drill is located in the center of a hypothetical sphere. The results show that the overall sound pressure level based on ANSI S5.1-1971 is equal to 93.63 dB. It is also seen that a gradual increase in sound pressure generated by rock drill from frequency of 31.5 Hz to 4000 Hz with a fall in 1000 Hz frequency is due to sound level meter in a frequency analysis of 1/1band octave.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
